用2-硝基-5-(N-甲基-N-十八烷基)氨基苯甲酸(NMOB)和花生酸制备了200层的交替多层膜,测得其二次谐波信号强度与NMOB层数的平方成正比.论文着重讨论了NMOB的Y型膜和它与花生酸的交替膜中的取向,并对两者之间的不同作了初步的解释.
An alternating multi-layer film of 200 layers was prepared with 2-nitro-5- (N-methyl-N-octadecyl) aminobenzoic acid (NMOB) and arachidic acid. The second harmonic signal intensity NMOB layer is proportional to the square.The paper focuses on the NMOB Y-membrane and its alternating membrane with arachidic acid orientation, and the difference between the two made a preliminary explanation.
